Planetary orbits that are more elliptical have a greater

From the 6 characteristic orbital elements  of the orbit of a body around another more massive, its eccentricity will indicate the shape of the orbit.

Now, going to the specific case of planets, according to Kepler's 1st Law, the planets revolve around the Sun in elliptical orbits.

In this context, the ellipse is a conic, whose eccentricity is between 0 and 1:

When its value is 0 we are talking about a circular orbit and when it is 1, a parabolic orbit.

That is, the nearer to the value of 1 (without reaching 1) the eccentricity of the orbit is, the more elliptical it will be.

Therefore, Planetary orbits that are more elliptical have a greater eccentricity.

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
